' Be it'known that I, TONY ALEXANDER, a

citizen of the United States, residing at Brookhaven, in the county of Lincoln and State of 5 'Mississipph have invented certain new and useful Improvements in Excavator-Shovels,

of which the following is a specification.

.This invention'has relation to scoops-.or

shovels designed for excavating, dredging,

1o loading, and unloading and wherever ashovel of the scoop type is adapted for use in scraping,

leveling, and digging.

One of the principal objects of the inven- 'tion isthe provision of a shovel of the lass I5. aforesaid which will be braced;a11d

every possible direction and admit of the puiiing` and dumping strain being applied` in such a manner as -not to affect the structure i of theshovel and which will have landside- 2o bars to obviate side draft and insure move-y knowledge of the details of construction of z 5 'the means for effecting the result reference is to be had to the following descriptionand accompanying drawings, in which- Figure 1 is a perspectiveview of a shovel embodying the lnvention. tral longitudinal section thereof, end portions of the draft-bars being broken away.' Fig- 3 is a detail erspective view of the frontend portion ofp a landside-bar having a portion of the share attached thereto. Fig.

3 5 4 is a perspective view of the V-shaped brace connecting the share with the shovel, the same being illustrated on a smaller scale. Fig. 5 is a detail perspective View ofthe front end portion of a landsidebar and the lower end ofthe standard or brace attached thereto.

Corresponding and'like parts are referred 1 to in 'the followin description and indicated in all the views o the drawings by the same reference characters.

The shovel or scoop 1 is of usual form in devices of the class herein referred to, its rear portion being of bowl form and its sides slop-- lng forward and downward. The front edge ofthe bottom portion of the scoop or shovel is indented and of V form, so as to provide' forwardly-diverged cutting edges. A share 2 of `V form abuts at its rear edgelagainst the corresponding edge of the shovel andta ers to a knife-edge, as'sliown mostclearly in' igs.

a cutting edge, and thereby-.add materially vto the efliciency ofthe device. The outer extremities of the share 2 are bent downward,

as shown at 3, and lie alongside of the forward ends of the landside-bars 7, to which they are attached in any substantial manner.

A brace 4 underlaps the abutting edge portions of the share 2 and shovel or scoo l 1' and 1s attached to each by rivets or like astenings. `The brace 4 is of V form, crresponding to the share 2, and its end portions 5 are bent ap roximately ata right angle and lie against t e inner sides of the lower end portions of the standards or braces 6, to which they arebolted or otherwise attached.

The landsidebars 7 extendzin arallel relation, and their front ends are thickened, as shown at 8, either b having blocks welded eterminate Way. The thickened .ends 8 are beveled to provide points 9, Whichpenetrate the earthor material to be loaded in the operationl of the shovel. A shoulder 10 is formed atV the rear end of the thickened part 8 for the front edge as to provide a -rigidstructre The landside-bars prevent side draft of the shovel when 4in operation and insure thereof in a direct line.

Draft-bars 12 extend approximately in parallel relation and are arran edf in the plane of the upper edge portion of t e shovel or scoop and are attached to the sides of the latter near their rear ends and to the/forward portion of the shovel by means of the standards or braces 6 and by means of cutters 13 and braces 14. Clevises 1 5 are fitted to the ends of the draft-bars 12, and draft-chains 16 are connectedfA thereto and to a draft-ring 17 to whichfoperating ropes or cablesare attached. Crossed braces 1,8 connect the draft bars 12 intermediate of their endsQj' The braces- 14 are attached at'their upar f' ends to f he draft-bars and incline rearwar movement ownwardly and have their lower end .8o of the standard or brace 6 to'abut against, Aso

and are attached at their upper ends to the draft-bars l2 end et their lower ends to the front ends of the lendsideba '7. 1li-eline` 19 encircles the rear portion of the shove or scoop and is etteched at its ends to the draftbars 12.

In operation the draft is applied directly to the foremost draft-chains 16, thence to they shovel or scoop through the draft-hors 12 and intermediate connections, thereby distr1huting the strsin throughout the shovel in c way to obviete injurious strain upon any one point and with the further result oi causing the shovel to run true and steady, the lend-- side-bars 7 materially assisting in the atteinment oi' these ends as welles forming runners. Nhe'n the shovel is utilized for carrying a load from one point end dumping it at another point, a.

controlling-cable is hitched to the resrmost draft-chains, and the .nailing-cable is attached to the foremost dra t-chains and in the advance of the lshovel to catch upthe load, the pull is on the advance draft-chains, and when the' load is to be dumped the controllingcable is held taut and the pulling-cable slackened, thereby permitting the shovel to swing downward at its front edge and discharge the load. The cutters i3 facilitate the separation of the earth at the sides of the slice formed by the' share 2 in the advance ofthe shovel 1`. A. shovel or scoop of. the type described` having its front edge indentedend approximately' of V form, a share of V forni 'hav-ing bent terminals' end having its rear edgey abuteniov ting against the front edge of said shovel, a

3. In combination, a shovel or scoop ofthe type described, draft-bars secured to the up per side portions of the shovel andprovided at vtheir ends with draft devices, and brac r connecting said draft-.bars and arranged ove the shovel to stay the same.

il. In combination, a shpvel or scoop of the type'describeyd, draft-bars at opposite sides thereof, landside hars having theiriront ends connected with the forward portion of the shovel, and standards between the draftbars, landside-bars and scoop. Q

5. In combination, a shovel or scoop ofthe ty eA described; landside bars at opposite sidies of the shovel and having their ont ends, .beveled to form penetrating points draft-bars, and connectmg means between the ydraft-hars, landside-bers andlshdvel.

6. l.In combination, a shovel or sc'n of the type described, draft bars, land'si e bars having their forward ends thickened and beveled to provide penetrating points, standards connecting the draft-bars with .the landsidehars and abutting at their lower front edges against the sli-ou ders formed by said thickcned. parts or" the latter.
